Britney considers $10m offer to join X Factor

Britney Spears is considering an offer to join the US version of the X Factor.

Britney Spears has reportedly been offered $10 million ($NZ12m) to judge the US version of The X Factor.

The Hold It Against Me singer's fiance and manager Jason Trawick is said to have "been negotiating for some time", with executives for the talent search show.

One source told E!News Spears has been offered the huge sum to appear on the second series of the show - which returns later this year - but she's said to be holding out for $16 million (NZ$19.5m).

The first run of The X Factor was judged by show boss Simon Cowell, LA Reid, Nicole Scherzinger and Paula Abdul, although the latter two were subsequently axed after it failed to achieve the ratings Simon had hoped.

Cowell is said to have initially approached Spears, and recently admitted he was "fascinated" by her and thinks she would be ideal for the show.

He said: "I would think that if she's managed to sustain in her family life in a career which is tough, this is a walk in the park."

Janet Jackson was also rumoured to have been offered the judging role, but turned it down because of touring commitments.

A high ranking executive for the show told The Hollywood Reporter the perfect candidate would be someone based in Los Angeles with not just success in the music business, but who is also a parent who wants to spend time with their children.
